本文应用甘肃省嘉峪关、兰州、天水地磁台2003--2006年4年地磁垂直分量Z的资料分析了静日S。日变形态、日变幅度以及日变形态畸变的变化特征。结果显示，不同台站日变形态基本相似；包含在日变形态畸变现象的低点位移和拉平现象具有明显的季节性变化规律，其在地磁冬季出现的概率远远高于其他季节，与日变幅变化关系密切。

Based on 2003--2006 geomagnetic data of vertical component Z produced by Jiayuguan, Lanzhou and Tianshui observatory in Gansu province, we analyzed the characteristics of Sq variation, daily range and shape distortion. The result shows that in the different observatories, the daily shape is very similar. The lowest point displacement and flattening phenomenon, included in the shape distortion, usually occur in geomagnetic winter and show significant rules in Gansu province, which is closely related with daily range.
